Title: Unitized injector modified for ultrasonically stimulated operation
Inventor: GIPSON LAMAR HEATH
IPC: F02M57/02
Filed: 2001-12-06
Abstract: An ultrasonic fuel injector (31) for injecting a pressurized liquid fuel into the combustion chamber of an internal combustion engine that uses an overhead cam (27) for actuating the injector, includes an injector body and an injector needle. The injector needle (36) is disposed within the body (33) and includes a magnetostrictive portion (38) disposed in the region of the body defined by a ceramic wall (40), which is transparent to magnetic fields changing at ultrasonic frequencies. A wire coil (42) is wound around the outside surface of the ceramic wall and connected to a source of electric power (16) that is controlled to oscillate at ultrasonic frequencies during predetermined intervals of operation of the injector. A sensor (51) is configured to signal when the overhead cam (27) is actuating the injector to inject fuel into the combustion chamber of the engine. The sensor (51) is connected to a control (47) that is connected to the power source (16) and is configured to operate same only when the overhead cam (27) is actuating the injector to inject fuel into the combustion chamber of the engine. When the power source (16) activates the oscillating magnetic field in the coil (42) and applies same to the magnetostrictive portion (38) of the needle, ultrasonic energy is applied to the pressurized liquid. A method involves retrofitting conventional injectors with needles having magnetostrictive portions and wound coils configured and disposed so as to subject the magnetostrictive portions of the needles to ultrasonically oscillating magnetic fields.

Inventor: LICHTENBERG JAKOB
IPC: G06F17/50
Filed: 2001-11-30
Abstract: A complex product is composed of several parts, where each part may depend on the other. As a consequence of these inter-dependencies, the selection of one part might exclude other parts from being included in the finished product. A  consistent configuration is a selection of parts where all inter-dependencies are satisfied. A computer program for computer-assisted configuration helps an end-user to make choices that will lead to a consistent product. The preferred embodiment of the present invention, Virtual Tabulation, is a method for keeping track of inter-depencies a large number of parts, to allow for the construction of an efficient and exact configuration program. Such a program allows interactive configuration over networks (e.g., the Internet). Another aspect of the invention, called Smart Search, allows a set of inter-dependencies among parts to be computed from a product database.

IPC: G01R33/54
Filed: 2002-02-21
Abstract: A method and apparatus for evaluating acute stroke patients and for determining whether a stroke patient will benefit from the use of thrombolys is therapy includes obtaining measurements of the cerebral blood flow and cerebral blood volume of the brain of a stroke patient, determining ischemic areas of the brain where the ischemic areas comprise the measurements of cerebral blood flow which are less than a first value and creating a penumbr a- infarct map of the ischemic areas of the brain using the measurements. The infarct area corresponds to the area of the brain where cerebral blood volum e is less than a second value. The penumbra area corresponds to the area of th e brain where cerebral blood volume is greater than this second dvalue. The method also includes determining a ratio of penumbra size to the total of penumbra size and infarct size. When the ratio is greater than a predetermin ed value, the stroke patient is a candidate for thrombolysis therapy.

Title: Wireless programmable logic devices
Inventor: ERICKSON BRIAN D
IPC: G06F17/50
Filed: 2002-01-30
Abstract: A wireless programmable logic device (102) contains a wireless component (110) and a programmable logic component (106). A remote wireless host (132) can be used to program the programmable logic device (102). Some product designs require multiple programmable logic devices. When wireless programmable logic devices are used in the design, all of them can receive data and commands from the host. As a result, the wireless host can control the order of configuration and the start time of these logic devices. There is no need to build glue logic for this purpose. Consequently, the efficiency in product design is improved. If there are problems in programming a programmable logic device, the host can log the failed operation in its memory. This information could be used to improve production flow.

Title: Authenticated electronic document management system and method
Inventor: DESROCHERS JOHN
IPC: G06F21/00
Filed: 2002-07-26
Abstract: The invention provides a system and method for establishing and managing authenticated electronic documents (e.g. commercial contracts) whereby the content, revision status and authenticating parties are stored, tracked, retrieved and validated on demand by permitted users. Variable document data is input by user into an electronic form template and this data is captured by the system. The system derives a document number and revision number for the document and all of this identifying information is associated with the document and stored. A document digest formula is applied to generate a unique document digest. The system then generates a unique barcode for each page of the document based on the digest, document number, revision number and paging details and the barcodes are electronically added to the associated pages of the document. Either the parties to the document sign a printed copy of the barcoded document or a digital signature is applied using a third party validation service. The resultant signed and barcoded document is stored electronically whereby permitted users may locate existing documents (e.g.  contracts), track document revisions and validate document contents and signatories.
